    Course: Remotely sensed information for crop monitoring and food security 2016
    Also available in:

    This course describes how the information derived from remote sensing is obtained and best used for crop monitoring in a food security context. It outlines what the exact meanings of the products are and shows how their early warning and food availability information contents can be combined efficiently with other sources (e.g. households surveys, market analyses, nutritional surveys, etc.)

    While population growth and economic development are putting unprecedented pressure on renewable, but finite water resources, especially in arid regions, scarce land and water resources are affecting food security and sustainable water management. FAO identified the need to implement a digital database built upon remote sensing and information technologies that can monitor and report on agricultural water productivity over Africa and Near East, accessible through the FAO Water Productivity through Open access of Remotely sensed derived data portal (WaPOR). The WaPOR database is now operational at continental level (all African and Near East countries covered by the 250 m spatial resolution data), national level (two beneficiary countries can access the WaPOR database at 100 m resolution) and subnational level with a spatial resolution of about 30 m, so far including eight areas of interest (river basins or irrigation schemes). Water Accounting Plus (WA+) reports based on remote sensing have been completed for three river basins as planned (Litani in Lebanon, Awash in Ethiopia and Jordan basin). An action framework at national level for capacity building and participatory decision making is currently being developed to make effective a “demand-driven” approach based on national and local needs.

    The world’s forests provide vital economic, social and environmental benefits. They supply wood and non-wood forest products, support human livelihoods, supply clean water and provide habitat for half the species on the planet. However, approximately 13 million hectares of forest are converted to other land uses annually worldwide. This forest clearing along with other forestry related activities is responsible for about 17 percent of human induced greenhouse gas emissions. International process es related to forests demand accurate information on tree cover and forest resources. Since 1946, the Food and Agriculture Organization of the United Nations (FAO) provides detailed information on the world’s forests, their extent, their condition and uses at 5 to 10 year intervals. For the Global Forest Resources Assessment 2010 (FRA 2010), a systematic, comprehensive, global survey of forests based on remote sensing imagery is being undertaken.
